I'm looking to build a comprehensive "Command Center" dashboard for Kubernetes that helps identify issues and understand their causes with both basic and advanced metrics. I want to track various metrics like node and pod CPU/RAM usage, disk I/O, filesystem pressure, network throughput and latency, pod restarts, API server latency, scheduler and etcd health, as well as saturation and backlog levels. The dashboard should also display Kubernetes events and error/warning log streams, with options for drilldowns from nodes to pods, and a way to link to a cluster topology view. Eventually, I'd like it to support switching between multi-cluster environments (like TEST and PROD).
I want to use an open-source stack, preferably one that incorporates Helm, and I'm curious about recommendations for components or agents that can help aggregate rich metrics, events, and logs into a unified interface. Additionally, I'd appreciate insights on best practices for dashboard layouts, including filters and drilldowns that incorporate per-namespace views while considering pitfalls I should watch out for from real-world operations.

Instead of building from scratch, consider creating a plugin for Headlamp. It’s part of the Kubernetes project and can save you a lot of effort while making it easier for others to adopt. Plus, it might be a great way to open up for community contributions!
For your Kubernetes Command Center, I recommend using Loki for log aggregation, Grafana for visualization, and Prometheus for metrics collection. This combo gives you a robust stack to display everything clearly. You can easily set filters in Grafana for different namespaces and customize alerts based on the metrics you gather. It also handles multi-cluster setups gracefully with the right configuration!
That’s a solid idea! I didn’t realize Headlamp was so flexible. Thanks for the tip!
